摘要：The invention relates to a method and apparatus for fault detection of electric glass panes in an electric glass pane system (1, 2, 7) operated with time-switched-type of input power feed control. According to the method, the mains power feed conductor (2) of the electric window pane system (1) is adapted to pass through a transformer assembly (13) so that electric power is transferred to the magnetic circuit (3) of the transformer (13), the electric power level in the magnetic circuit (3) of the transformer (13) is detected, and to the magnetic circuit (3) of the transformer (13) is additionally fed electric power via an auxiliary power feed circuit connected in parallel with the input feed power controlling switch (7), whereby the magnetic circuit (3) of the transformer (13) is kept energized at all times as long as all the panes (1) of the electric window pane system are intact.
